The map reveals that across all areas of England, gonorrhoea diagnoses have risen, with London seeing the biggest spike in new cases.

Gonorrhoea is an STI caused by bacteria found in discharge from the penis and in vaginal fluid. It is spread through unprotected vaginal, oral or anal sex, as well as sharing unwashed vibrators and sex toys.

Using data from Public Health England , euroClinix have created an interactive map showing the diagnose rates of people aged 45 and over for STIs including gonorrhoea, genital herpes, syphilis, genital warts and chlamydia.

According to the NHS, typical symptoms of gonorrhoea include a thick green or yellow discharge from the vagina or penis, pain when urinating and (in women) bleeding between periods.

However it's also important to note that around one in 10 infected men and almost half of infected women don't experience any symptoms at all.

The map shows that, overall, London has seen the highest growth in STI diagnoses, followed by the East Midlands. Meanwhile the West Midlands has the lowest number of diagnoses, followed by the North East.

Earlier this week, doctors warned of a drug-resistant type of "super-gonorrhoea" which is spreading across Britain.

Senior medics believe it may become untreatable.

The powerful strain of the sexually transmitted superbug was first seen in the north of England, but has since been found in the West Midlands and the South East, Public Health England (PHE) said.

The strain is "highly resistant" to the antibiotic azithromycin, meaning medics are relying on a second drug, ceftriaxone, to treat it.

But there are no other effective drugs to tackle it, raising the prospect of it becoming untreatable if it builds further resistance.

To avoid catching STIs, such as chlamydia and gonorrhoea, experts recommend using condoms during sex and avoiding sharing sex toys.
